HTTP caching is a process of temporarily storing web content and rich media—images, audio, and video—on a CDN server in a content distribution network (CDN), or content delivery network. In these large networks, content passes through multiple servers to reach the targeted destinations, so to reduce traffic in the primary network, HTTP caching stores copies of content on geographically dispersed servers to respond to requests from local users.
Delivering on-demand rich media content to subscribers from the cache on the nearest media streaming server not only reduces bandwidth consumption, it also enhances the user experience by eliminating perceived lag.
HTTP caching is no longer a novelty or a luxury. It's a requirement for network service providers facing exponential growth in network traffic as well as rising consumer expectations.
In recent years Internet traffic has exploded as more customers have adopted multiple devices—laptops, smartphones, and tablets. And when they consume content on any device, they expect consistent high-quality service wherever they are 24/7.
